Description
Technical Field
[0001] The utility model relates to the field of stainless steel strip edge trimming devices, in particular to an edge trimming device for stainless steel strips. Background Art
[0002] After the stainless steel strip is produced, there are burrs, bumps and other conditions on the edge, which makes it inconvenient to coil and pack. Therefore, the edges need to be trimmed before packaging to make the edges of the stainless steel strip smoother, which is convenient for packaging and transportation, and also beneficial for users. The trimming equipment generally uses a slitting machine or a trimming machine. The stainless steel strip's pinch roller conveying mechanism conveys the steel strip to one side of the slitting machine or trimming machine with two sets of symmetrically arranged blades, and trims both sides of the steel strip at the same time.
[0003] In the current stainless steel strip trimming process, the surface of the steel strip sent into the trimming machine or slitting machine by the clamping mechanism often carries dust particles. If the hard dust particles are on the axis of the blade cutting, the blade will be damaged during cutting, and it is also easy to cause uneven incisions. In addition, during the cutting process, a large amount of smoke and dust will be generated near the cutting point of the steel strip. The original trimming machine or slitting machine does not have the ability to absorb dust. During long-term cutting processing, smoke and dust accumulate in the cutting work area of the machine, which is easy to affect the continuous feeding of the steel strip and the stable cutting of the blade.
[0004] Therefore, in view of the fact that the hard impurities and dust on the surface of the stainless steel strip during edge trimming can easily cause contamination and damage to the blade, and there is no effective means to deal with the smoke generated by cutting, the scattered and accumulated smoke will pollute the working environment and affect the continuous feeding of the steel strip and the stable cutting of the equipment. A stainless steel strip edge trimming equipment with feeding dust removal and cutting dust suction functions can be designed. The existing steel strip edge trimming machine can be used in conjunction with an assembled dust removal and dust suction device to ensure the stable operation of the equipment while reducing the pollution of the environment to the cutting smoke.
